Introduction

Gears offer a way to transform an available input into a desired output. On bicycles, gears can make it easy to climb hills, or they can make it possible to boost speed, but they cannot do both at the same times.

Activity

The slideshow below gives you an introduction to gears, ending with an example of the graded assignment.
